Giambattista Vico’s Principj di una scienza nuova d’intorno alla comune natura delle nazioni, commonly known in English as The New Science, stands as one of the most ambitious and original works of philosophy in the early modern period. First published in 1725, with substantially revised editions in 1730 and 1744, this treatise attempts nothing less than to establish a systematic science of human history and culture, grounded in principles that Vico believed were as rigorous as those governing the natural sciences. Writing in Naples during the height of Enlightenment rationalism, Vico developed a profoundly different vision of human knowledge and historical development, one that would influence thinkers from the Romantic period through the twentieth century.
The work is a dense, often difficult text that combines philosophy, philology, jurisprudence, mythology, and what we would now call anthropology and sociology. Vico’s prose is notoriously challenging, marked by elaborate architectonic structures, recursive arguments, and a tendency to circle back repeatedly to his central themes. Yet beneath this complexity lies a coherent and revolutionary vision: that human history unfolds according to discoverable patterns, that nations pass through predictable stages of development, and that we can understand the past through careful attention to language, myth, law, and custom.
The Foundations: Vico’s Critique and Method
Vico begins by establishing his departure from the dominant philosophical currents of his time, particularly Cartesian rationalism. Where Descartes had argued that clear and distinct ideas, apprehended by pure reason, constituted the foundation of knowledge, Vico insists on a radically different principle: verum ipsum factum — “the true is the same as the made.” According to this principle, we can have certain knowledge only of what we ourselves have made. God has perfect knowledge of nature because He created it; humans, by contrast, can have only imperfect knowledge of the natural world. But humans can have genuine scientific knowledge of the civil world — the world of nations, laws, institutions, and customs — because this is a world that humans themselves have created.
This epistemological principle grounds Vico’s entire project. The New Science is possible precisely because human history is a human creation, and therefore accessible to human understanding in a way that nature is not. Vico thus inverts the Cartesian hierarchy: where his contemporaries sought certainty in mathematics and physics, Vico finds it in the study of human institutions and their historical development.
Vico’s method combines what he calls “philosophy” and “philology.” Philosophy provides rational principles and seeks universal patterns; philology attends to the particular facts of language, literature, law, and custom preserved in historical records. Previous thinkers, Vico argues, had erred by pursuing one without the other: philosophers constructed abstract systems divorced from historical reality, while philologists accumulated facts without understanding their underlying principles. The New Science would unite these approaches, using philological evidence to ground philosophical principles and philosophical principles to make sense of philological data.
The Three Ages and the Corso-Ricorso
At the heart of Vico’s system lies his theory of historical cycles. All nations, Vico argues, pass through three ages in a determinate sequence: the Age of Gods, the Age of Heroes, and the Age of Men. Each age is characterized by distinctive forms of government, law, language, and consciousness.
The Age of Gods represents humanity’s earliest stage, emerging from a bestial condition after the biblical flood. In this primitive era, humans live scattered in forests, without language, law, or social organization. The crucial transition occurs when thunder and lightning terrify these brutish creatures, leading them to imagine the sky as a great deity — Jove or Jupiter — expressing anger through storms. This moment of religious awe marks the birth of human consciousness and society. Humans begin to settle in fixed places, establish families, bury their dead, and develop the first rudiments of religion and morality. Government in this age is theocratic; the fathers of families rule as priest-kings, claiming divine authority. Law is understood as divine command, revealed through divination and augury. Language is mute or gestural, consisting of sacred signs and symbols. Poetry in this age is not artistic but theological — myths are not fictions but the only way primitive humans can think about their world.
The Age of Heroes follows as families aggregate into the first cities. This is an aristocratic age, dominated by a warrior nobility who claim descent from the gods and rule over a subordinate class of clients or plebeians. Heroic societies are characterized by extreme inequality and violence. The heroes possess all political rights; they alone can participate in government, own land, contract legal marriages, and access the law. The plebeians are essentially serfs, bound to the land and excluded from civic life. Law in this age is harsh and literal, expressed in solemn formulas and rituals. Language becomes metaphorical and poetic — the language of Homer and the early Roman laws. The heroes think in vivid, concrete images rather than abstract concepts. Their poetry celebrates martial valor and aristocratic virtue.
The Age of Men represents the full development of human rationality and equality. Through long struggles, the plebeians gradually win recognition of their rights, leading to popular or democratic governments, or to monarchies that govern in the interest of all citizens rather than a privileged class. Law becomes rational and equitable, based on universal principles rather than class privilege. Language becomes prosaic and abstract, capable of expressing philosophical concepts. Humans can now think in general terms, develop systematic philosophy and science, and recognize the common humanity of all people.
But this progress contains the seeds of its own destruction. As societies become more refined and rational, they also become more corrupt. The very equality and freedom of the Age of Men lead to license and disorder. Citizens become isolated individuals, pursuing private interests without regard for the common good. Skepticism and sophistication undermine the religious and moral foundations of society. Eventually, the social fabric disintegrates entirely, and nations collapse into barbarism — either through conquest by more vigorous peoples or through internal dissolution.
This collapse, however, is not the end. From the ruins, the cycle begins again — the ricorso, or recurrence. Humanity returns to a primitive religious age and begins the ascent through the three stages once more. Vico sees this pattern exemplified in the history of Rome and medieval Europe: ancient Rome passed through all three ages before collapsing; medieval Europe emerged from barbarism and began the cycle anew, with feudalism representing a return to the Age of Heroes.
Providence and the Heterogeneity of Ends
A crucial element of Vico’s system is his concept of providence. The regular patterns of history are not the result of human planning or conscious design. Indeed, humans typically act from narrow, selfish motives — lust, greed, ambition, the desire for security. Yet from these base materials, providence constructs the civil world. The brutish humans who first imagined Jove were motivated by fear, not philosophical insight, yet this fear led them to establish families and morality. The aristocratic heroes who monopolized power were motivated by pride and the desire to dominate, yet their conflicts with the plebeians eventually produced more just laws. Humans intend one thing; providence achieves another through their actions.
This is what Vico calls the “heterogeneity of ends” — the divergence between human intentions and historical outcomes. It allows Vico to maintain both human agency and historical necessity. Humans make their own history through their choices and actions, yet the overall pattern of development follows providential design. Providence works not through miracles or supernatural intervention but through the natural consequences of human nature operating under different historical conditions.
Vico’s providence is thus quite different from the Christian providentialism of his predecessors. It is immanent rather than transcendent, working through natural human passions rather than divine intervention. Yet Vico insists it is genuinely providential, not merely mechanical or deterministic. The order of history reveals divine wisdom, even if that wisdom operates through natural means.
Language, Myth, and Poetic Wisdom
One of Vico’s most original contributions concerns the nature of early human thought and expression. Against the rationalist assumption that primitive humans thought like modern philosophers but simply lacked knowledge, Vico argues that early humans had a fundamentally different mode of consciousness — what he calls “poetic wisdom.”
Primitive humans, lacking abstract concepts, thought entirely in vivid, concrete images. Unable to generalize, they created “imaginative universals” or “poetic characters” — mythological figures that embodied whole classes of things or actions. Jove was not an abstract concept of divinity or natural force but a concrete, terrifying image that represented all instances of thunder and divine power. Hercules embodied all heroic strength; Achilles all aristocratic rage and honor.
This explains the nature of mythology. Myths are not allegories concealing philosophical truths, nor are they mere fictions or lies. They are the necessary form of thought for people who cannot yet think abstractly. When Homer describes the gods intervening in human affairs, he is not inventing stories for entertainment but expressing the only way heroic-age Greeks could understand causation and agency. The myths are literally true as expressions of how their creators understood the world.
Language develops through parallel stages. The first language was mute — gestures and sacred signs. Then came hieroglyphic or symbolic language, using images to represent things. Only gradually did phonetic language emerge, and only in the Age of Men did language become capable of expressing abstract concepts. Even then, all abstract terms preserve traces of their concrete origins. Vico engages in extensive etymological analysis to show how philosophical vocabulary derives from bodily or material roots.
This theory of language and myth has profound implications. It means that we cannot simply read ancient texts as if their authors thought like us. We must reconstruct the mentality that produced them, understanding how different forms of consciousness express themselves in different forms of language and literature. It also means that poetry is not a late refinement but the original form of human expression — Homer was not an educated artist but the voice of an entire people in its heroic age.
Law, Custom, and Social Conflict
Vico’s training as a jurist deeply informs his historical vision. Much of the New Science traces the development of law through the three ages, showing how legal forms reflect and shape social consciousness.
In the Age of Gods, law is divine command, known through divination. The father of each family is its priest and judge, interpreting divine will. There is no distinction between law, religion, and morality.
The Age of Heroes sees the emergence of civil law, but in a harsh, aristocratic form. The heroes monopolize legal knowledge, keeping the formulas of legal actions secret. Law is rigidly formulaic — a single word out of place invalidates a legal act. This serves to exclude the plebeians, who cannot master the arcane procedures. The famous Roman law of the Twelve Tables, often celebrated as a foundation of justice, Vico sees as fundamentally aristocratic, designed to maintain class privilege.
The transition to the Age of Men occurs through social conflict — what Vico calls the “struggle between the orders.” The plebeians gradually force recognition of their rights: the right to legal marriage, to own land, to know the law, to participate in government. Each concession is wrested from the aristocracy through threat of secession or revolt. This conflict drives legal development toward greater equity and universality.
In the Age of Men, law becomes rational and humane, based on natural equity rather than class privilege. But this very rationality and flexibility can become a weakness. As law becomes more sophisticated, it also becomes more subject to manipulation. Clever lawyers can twist equitable principles to serve private interests. The corruption of law reflects the broader corruption of society in its final stage.
The Ideal Eternal History
Vico distinguishes between the temporal history of particular nations and what he calls the “ideal eternal history” — the universal pattern that all nations follow. No particular nation’s history perfectly exemplifies this pattern; historical contingencies, geography, and external influences create variations. But the underlying sequence of the three ages represents a necessary development grounded in human nature itself.
This ideal history is “eternal” not in the sense of existing outside time but in being perpetually repeated. It is the form that human history necessarily takes, given the constants of human nature and the providential order. Each nation traverses this path in its own way and at its own pace, but all follow the same fundamental trajectory.
Vico supports this theory through comparative analysis. He examines not only classical antiquity but also the histories of other peoples — the ancient Germans, the medieval Europeans, even reports of the New World. Everywhere he finds similar patterns: primitive religious ages giving way to heroic aristocracies, which in turn yield to more rational and egalitarian societies. The parallels between ancient Rome and medieval Europe are particularly striking: both show feudal aristocracies, struggles between nobles and commons, gradual legal development toward equity.
Homer and the Homeric Question
Vico’s theory leads him to a revolutionary reinterpretation of Homer. The Iliad and Odyssey, he argues, were not composed by a single learned poet but are the collective creation of the Greek people during their heroic age. “Homer” is not an individual but a poetic character, representing the Greek rhapsodes who preserved and transmitted these oral poems over generations.
This explains various puzzles about the Homeric poems: their inconsistencies, their vivid but unsophisticated style, their focus on aristocratic values, their anthropomorphic gods. These are not flaws but natural features of heroic-age poetry. The poems express the consciousness of an entire people, not the artistic design of an individual genius.
Vico’s Homer is thus radically different from the refined, philosophical poet imagined by Renaissance humanists. He is crude, violent, and superstitious — but authentically heroic. The poems are valuable not as moral instruction or artistic models but as historical documents, preserving the mentality of the Greek heroic age.
This interpretation anticipates modern Homeric scholarship, which would eventually confirm the oral-traditional nature of the epics. Vico’s insight that Homer represents a stage of cultural development rather than an individual genius was far ahead of its time.
The Ricorso and Medieval History
Vico’s most controversial application of his theory concerns medieval Europe. He argues that the fall of Rome and the barbarian invasions represented a return to primitive conditions — a new Age of Gods. Medieval feudalism was a new Age of Heroes, structurally parallel to ancient aristocratic societies. The struggles between nobles and commons in medieval cities recapitulated the Roman struggle between patricians and plebeians.
This means that history does not progress linearly but moves in cycles. The Middle Ages were not simply a decline from classical civilization but a necessary stage in a new historical cycle. Modern Europe represents a new Age of Men, comparable to late republican and imperial Rome.
Vico sees detailed parallels: medieval vassalage corresponds to Roman clientage; the feudal nobility to the Roman patricians; the rise of communes to the Roman plebeian movement; medieval customary law to early Roman law; medieval epic poetry to Homer. Even language shows parallel development, with medieval Latin becoming more abstract and philosophical as society advanced.
This cyclical view distinguishes Vico sharply from Enlightenment progressivism. History does not move steadily upward toward perfection but follows a pattern of rise and fall. The achievements of the Age of Men are real but fragile, always threatened by the corruption that luxury and sophistication bring.
Method and Evidence
Vico’s method involves careful attention to what he calls “philological proofs” — evidence from language, literature, law, and custom. He engages in extensive etymological analysis, tracing how words preserve memories of earlier social conditions. He examines legal formulas, showing how their archaic language reveals the mentality of earlier ages. He analyzes myths and legends as historical documents, reading them not for literal facts but for the social structures and consciousness they express.
This philological method is combined with philosophical reasoning about human nature and social development. Vico seeks to show that the evidence, properly interpreted, confirms his theoretical principles, while the principles make sense of otherwise puzzling evidence.
The result is a work of immense erudition, ranging across classical literature, Roman law, medieval history, and contemporary reports of non-European peoples. Vico draws on an extraordinary breadth of sources, though his interpretations are often idiosyncratic and sometimes forced. His etymologies, in particular, are frequently fanciful by modern standards, though the underlying insight — that language preserves social history — remains valid.
Vico’s Context and Significance
Giambattista Vico lived his entire life in Naples, serving as professor of rhetoric at the university. He was largely isolated from the main currents of European thought, writing in Italian rather than Latin at a time when Latin remained the language of international scholarship. The New Science received little attention during his lifetime and was virtually unknown outside Italy.
Yet Vico’s work represents a profound challenge to Enlightenment assumptions. Where his contemporaries emphasized reason, progress, and universal human nature, Vico stressed imagination, cycles, and historical particularity. Where they sought to judge all societies by rational standards, Vico insisted on understanding each society in its own terms. Where they saw primitive peoples as simply ignorant, Vico recognized different modes of consciousness.
The work’s influence grew slowly. In the nineteenth century, Romantic thinkers and historians discovered Vico as a precursor, appreciating his emphasis on imagination, his respect for myth and poetry, and his historical sense. Jules Michelet translated the New Science into French and saw Vico as anticipating his own historical method. Later, philosophers like Benedetto Croce and R.G. Collingwood found in Vico a philosophy of history that made human self-understanding central to historical knowledge.
In the twentieth century, Vico’s influence extended further. His theory of myth influenced anthropologists and students of comparative religion. His philosophy of language anticipated aspects of structuralism and hermeneutics. His cyclical view of history resonated with thinkers disillusioned with progressive narratives. Isaiah Berlin championed Vico as a founder of the counter-Enlightenment, emphasizing cultural pluralism and the limits of rationalism.
The New Science remains a difficult, often frustrating work. Its organization is labyrinthine, its prose dense, its arguments sometimes circular. Vico revised it repeatedly, adding new material without fully integrating it, creating layers of argument that don’t always cohere. Yet its central insights — that human history is intelligible because it is a human creation, that different ages have different modes of consciousness, that we must understand the past in its own terms rather than imposing our categories — have proven enduringly influential. Vico’s vision of a science of human culture, grounded in historical understanding rather than abstract reason, helped establish the human sciences as a distinctive domain of knowledge, neither reducible to natural science nor inferior to it.
